[Inspiration comes from "Maze Rice", "Abnormal Shura", "Fullmetal Alchemist" and "Goblin Lair"] There are very few people left who know what happened three hundred years ago. The world has lost so much, but no one can tell exactly what was lost. It's just that in this world, human science and technology has not made significant progress for three hundred years. Dwarves are timid and can only hide underground. Many half-elves have fallen into the world, halflings complain all day long, goblins are almost extinct, goblins are extreme and narrow-minded, dragons have no desires, and sirens will never sing again... After three hundred years, the world seems to have become better, but in fact it is still a mess.
